Treatment of osteopenia and osteoporosis in renal transplant children and adolescents
Abstract
Successful renal transplantation corrects many of the metabolic abnormalities associated with the development of renal osteodystrophy, but despite a well-functioning graft osteopenia, growth failure, spontaneous fractures, and avascular necrosis remain prevalent in adult and pediatric kidney recipients. A paucity of information exists regarding the effects of different therapies to prevent and treat bone loss in the renal transplant recipients. We constructed a design to study the effect of different modalities of treatment on bone mass in our renal transplant children. Among 93 patients who underwent renal transplantation at the age of 17 yr or less and were subjected to dual-energy X-ray absorptiometry (DEXA), we blindly randomized 60 patients who had osteopenia or osteoporosis (T-score = -1 by DEXA) in a prospective study. Their mean age at time of transplantation was 13.4 +/- 4.3 yr. The mean duration after transplantation was 48 +/- 34 months. The patients were classified randomly into four groups. Each group consisted of 15 patients: group 1 was the control group, group 2 received oral alfacalcidol 0.25 microg daily, group 3 received oral alendronate 5 mg daily, and group 4 received 200 IU/day nasal spray calcitonin. Parameters of bone turnover, calcium metabolism, and DEXA were measured before and after 12 months of treatment duration. The characteristics of all groups were comparable at the beginning of the study. At the lumber spine, bone mass density decreased from…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 93 participants or records.
